I think we are confusing the two things here. One is actual digestion of what we eat, which doesn't happen with the fiber. Thus the body doesn't get any nutrition. The second is what fiber does to help the digestive tract. As Malkavian stated correctly, insoluble fiber makes the food move faster, which is good provided your gut can handle it. Soluble fiber doesn't digest either, but helps by padding the gut lining. It also works as a pre-biotic - food for the colon bacteria. There was never any question about
the usefulness of fiber. Of course one should eat plenty for fiber with the meat. All I was saying was that the stomach, and small intestine, where the actual digestion happens would work harder on trying to digest fiber than meat. Meat may take longer, but it still digests completely (and provide nutrients such as vitamins D, and B12 that are essential). I think fiber makes our guts work just as much in 6 hours while passing by as the meat would in 1 to 3 days. That is just my thinking (I would buy into any logic that supports eating meat...)
